"UNITED ARTHUR J. PERKINS, OF REVERE, MASSACHUSETTS, ASSIGNOR TO BOSTONELECTRIC COM- PANY, OF BOSTON, MASSACHUSETTS, A CORPORATION OFMASSACHUSETTS.

ELECTRIC HAND-LIGHTING GAS-BURNER.

To all whom it mug, concern:

Be it known that l, ARTHUR J. Punmxs, a citizen of the United States,residing at Revere, in the county of Sullolk and State of Massachusetts,have invented new and useful Improvements in Electric Hand- .l iightingGas-Burners, of which the follow ing is a specification.

This invention relates to that class of elec tric hand-lightinggas-burners of the pull down type in which the pulling down of an arm orlever turns on the gas-cock and at the same time swings aspring-electrode into contact with an electrode at the burner-tip, thusigniting the gas by an electric spark, the gas being turned off by areverse movement of the arm or lever; an example of an invention of thisclass being illustrated and described in Letters Patent of the UnitedStates dated June 26, 1900, and numbered 652,430. In burners of thisgeneral description there has been much complaint that the movable pinwhich has been employed in connection with the swinging electrode isliable to stick, and thus the cone-spring is unable to rise into contactwith the electrode at the tip. This tendency to stick is by reason ofthe fact that when the burner is on the fixture there is very soon anaccumulation of dust and dirt, clogging the pin. This necessitates theburner being fre quently repaired or discarded.

My present invention has for its object to produce an improvedconstruction whereby the movable electrode pin is entirely discarded,whereby the burner is rendered iore simple in construction and efiicientin operation, and whereby the danger of the parts being out of repair isreduced to a minimum.

The nature of the invention is fully described in detail. below, andillustrated in the accompanying drawings, in which Figure 1 is a frontview of my improved burner with the gas turned oil. 2 is a similar viewwith the spring-electrode making contact with the electrode at the tipduring the act of turning on the Fig. 3 is a similar view taken whilethe gas is being turned off just before the spring-electrode has reachedthe point where it passes under the electrode at the tip without makingcontact with it. Fig. 4 is a side view with the parts in the sameposition as in Fig. 3. Fig. 5 is an elevation of the plate or memberSpecification of Letters Patent.

which is mounted on the spindle of the gascock, removed. F 6 is a viewin elevation of the electrodc-carrying l .ver removed.

Similar numerals of reference indicate corresponding parts.

is the gas-cock, constructed as usual. .lilounted on the spindle of thegas-cock and adapted to be rotated thereby by means of the straight edge16 of the opening 17 is a plate or disk whose main portion or hub 18 isprovided with a pair of teeth 19, which are adapted to strike onopposite sides of the pin 20 which extends horizontally from theburner-pillar, thus limiting the rotation or reciprocation of the plateor disk.

'ihus far the parts described are not new in this invention.

The plate 18 is provided with a substantially radial arm 21 which isprovided with a horizontally extending pin 22. A sytj iral spring 23connects the pins 20 and 22. ivotally connected at 2 1 to a small radialextension 25 integral with the plate 18, is the arm 26 of an elbow-leveror lifting-lever which comprises said arm 26 and the arm 27. The arm 27is broadened at 28 near the pivot 24-, and this broadened portion isprovided with a slot 29 elongated in line with the arm 27, into whichslot extends the spindle of the gas-cock 15. Furthermore the arm 27 isbroadened diagonally at 30 in order to provide the diagonal slot 31 intowhich the pin 22 extends. The outer end of said arm 27 is formed intocone-shape 32, and at said end the arm is provided with the coiledspring 33 whose upper end is formed into the electrode point 34.

When the gas is turned oil, as illustrated in Fig. 1, the arm 26 of thelilting-lever is elevated, and the arm 27 is swung down resting bygravity by means of its slotted portion 30, 31 on the in 22 whichextends from the arm 21 of the risk or plate 18, said arm 21 being helddown toward the lelt by the power of the spring 23 which connects thepins 22 and 20, and the further swinging down of the arm 21 beingprevented by the left hand tooth 19 which bears against the pin 20 andlimits the rotation of the disk 1.8. \Vhen the gas is turned on, theWire or cord 35 is pulled, drawower edges of the slots 29 and 30 firstswing up against the spindle of the gas-cock 15 and against the pinrespectively, and thus the slotted arm 27 swings up the arm 21, imparting rotation to the disk 18 against the power wnicn is pivotallysupported by the disk or of the spring 23, and the electrode point 34 isbrought up toward the electrode 11, until when it reaches the positionillustrated in Fig. 2 it makes contact and turns on the gas. After theelectrode point 3% has swung toward the right under and out of contactwith the electrode 11, the continued pull on the wire 35 causes the arm27 to pull the arm 2]. by the center, and the spring 23 holds the partsin an open position with the right hand tooth. 19 hearing against thepin When the gas is to be turned off the lifting of the arm 26 of thelever first causes the arm 27 to swing to the left, and drop with theupper edges of the slots 31 and 29 resting upon the pin 22 and gas-cock15 respectively, the drop being sufiicient to lower the upper end of theelectrode point 34 so that it is able in its movement toward the left toclear the electrode 11 and to make no contact with it as it moves underit, the position of the parts as the electrode 3% is approaching (andbeing under) the electrode 11 being well illustrated in Figs. 3 and l,in which the lever is seen to be resting by gravity with the upper endsof the said slots in contact with the pin 22 and gas-cock 15. As theupward pressure on the arm 26 is continued the spring 23 pulls down thearm 21 and draws the parts into the position illustrated in Fig. 1,turning oil the gas.

It will be seen that the operating lever is one integral piece of metal,and that when the cord or wire is pulled the spiral spring 33 is notmoved with relation to the lever as it is in a fixed position thereon.It is not raised by any bolt or pin which moves or slides with relationto the lever, but it is raised directly by the lever itself. Itsmovement therefore is positive and not relative to that of the lever,and there is no opportunity for any of the parts to stick or becomeclogged by the accumulation of dust or dirt. As long as the lever can beoperated the electrode will swing up and make contact, and will swingback without making contact.

Having thus fully described my invention,

What I claim, and desire to secure by Letters Patent is 1. in anelectric hand-lighting gas-burner provided with an oscillating gas-cock,the burner-pillar, a fixed electrode supported by the pillar, a disk orplate rigid on the spindle of the gas-cock, means for limiting therotation of the disk, an elbow-lever one arm of plate at one side of thecenter of the disk and the other arm of which is provided with alongitudinal slot near its inner end into which the gas-cock extends andwith a diagonal slot between the longitudinal slot and the outer end ofthe arm, a pin extending from the disk through the diagonal slot, aspring connecting said pin with the burner-pillar, and an electrodefixed directly to and upon the outer end of the slotted arm of thelever, for the purpose set forth.

2. In an electric hand-lighting gas-burner provided with an oscillatinggas'-cock, the burner-pillar, a fixed electrode supported by the pillar,a disk or plate rigid on the spindle of the gas-cock and provided with asubstantially radial arm, means for limiting the r0- tation of the disk,an elbow-lever one arm of which is pivotally supported by the disk orplate at one sine of the center of the disk and the other arm of whichis provided with a longitudinal slot near its inner end into which thegas-cock extends and with a cam-slot between the longitudinal slot andtheouter end of the arm, a pin extending from the arm on the diskthrough the cam-slot, a spring connecting said pin with theburner-pillar, and an electrode fixed directly to and upon the outer endof the slotted arm of the lever, whereby swinging the lever in onedirection turns on the gas and brings the electrode thereon into contactwith the electrode supported by the burner-pillar and swinging it in theopposite direction turns oil the gas and allows the slotted arm of thelever and the electrode thereon to pass under the electrode on theburner-pillar without contact there with.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
